My personal take is that film is cooling down a bit from the pandemic high. Part of it is the same financial concerns affecting everyone. A friend and musician who frequently sells/trades gear has seen interest wane similarly.
This ties in with the point I was attempting to make above. I'm the sort of person that hung on to my turntable and LP's after CD players came along, who hung on to my film gear after digital cameras came along, who is still clinging on desperately to my cars with manual transmissions, etc., etc.. I've watched the values of all these things rise rapidly over the past few years. While it appears to me that such things are still selling for quite a bit more now than they were pre-pandemic, I have seen them all cool down to some degree more recently.
You can't rule the possibility that they might enjoy increased popularity for some time yet to come. It seems that part of what kicks off any trend in renewed interest for old tech is often a low price of entry. Given their low prices, early digicams no doubt appeal to a lot of people who might be interested in using a dedicated camera for photography (instead of their smartphones) but don't have a whole lot of money to play around with. Given that there are others out there generating excitement about early digicams, it's easy enough to give one a try when they can still be found for cheap. Beyond a certain price point however, all bets are off.Maybe those early 2000’s digicams will take over after all.
